[LLVMdev] Adding a Buildbot Config

[greened at obbligato.org]

The document here explains pretty well how to add a buildslave to the
buildbot:

http://llvm.org/docs/HowToAddABuilder.html

However, it's not clear to me how to add a new build config.  I would
like to add a buildslave that builds with -Werror so we can catch and
correct warnings early.

How should I go about adding a new build configuration?  Do I edit
one of the .py files in zorg?

Thanks!
